Mont. Code § 20-3-311
The members of the trustees of any district may not receive compensation for their services as trustees, except that the secretary of the trustees of a high school district operating a county high school or the secretary of a joint board of trustees may be compensated for services as the secretary. The members of the trustees who reside over 3 miles from the trustees' meeting place must be reimbursed at the rate as provided in 2-18-503 for every mile necessarily traveled between their residence and the meeting place and return in attending the regular and special meetings of the trustees, and all trustees must be similarly reimbursed for meetings called by the county superintendent. The travel reimbursement may be accumulated during the school fiscal year and paid at the end of the fiscal year, at the discretion of each trustee.
